BS 4515-1:2009

This standard BS 4515-1:2009 Specification for welding of steel pipelines on land and offshore is classified in these ICS categories:

• 23.040.10 Iron and steel pipes

This British Standard specifies requirements for the welding of carbon, carbon manganese and low alloy steel pipelines with specified minimum yield strengths not exceeding 555 N/mm² (grade L555 as specified in ISO 3183:2007 and BS EN 10208‑2:1997) and designed in accordance with PD 8010‑1 and PD 8010‑2.

The standard applies to pipes of outside diameter 21.0 mm and larger having a thickness of 3.0 mm or greater and is applicable to transmission pipelines for gases, liquids or slurries, both on land and offshore.

In addition to the definitive requirements, this standard also requires the items detailed in Clause 4 to be documented. For compliance with this standard, both the definitive requirements and the documented items have to be satisfied.

Information on hyperbaric welding is given in Annex A and information on brazing and aluminothermic welding of anode bonding leads is given in Annex B.

Additional recommendations for the welding of corrosion resistant alloy clad and lined pipelines are given in Annex G.
